Abstract
The present invention relates to a solid oxide fuel cell in which an anode is formed with a hollow portion, and the hollow portion may be used as a gas diffusion path, thereby improving gas diffusion performance, and the hollow portion may be also used as a reinforcement hole for reinforcing a strength or a current collecting hole for increasing a current collecting efficiency, thereby improving a cell strength and also increasing an efficiency of producing electric energy. The solid oxide fuel cell has an electrolyte layer; an anode; a cathode; and a hollow portion formed in the anode.
Claims5
A solid oxide fuel cell, comprising:
- an electrolyte layer;
- an anode and a cathode respectively formed to be contacted with both sides of the electrolyte layer;
- and
- a plurality of current collecting members each comprising a current collecting layer provided on an outer surface of the anode only
- wherein hollow portions are formed in the anode;
- wherein a first group of the hollow portions form gas diffusion paths;
- wherein a second group of the hollow portions form reinforcement holes, and reinforcement members are respectively inserted into the reinforcement holes;
- and
- wherein a third group of the hollow portions form current collecting holes, and the current collecting members are respectively inserted into the current collecting holes.
